The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The embodiment provides a wiring terminal which can be used on low-voltage electrical appliances needing wiring, such as button signal lamps.

As shown in fig. 1 and 2, the connection terminal includes a housing 1, an elastic portion 2, a connection portion 3, and a pushing member 4. The shell 1 is a main appearance piece and a main mounting piece of the wiring terminal, a mounting cavity is formed in the shell 1, the elastic part 2 and the wiring part 3 are mounted in the mounting cavity, and part of the structure of the pushing part 4 is also arranged in the mounting cavity. The elastic part 2 has two ends, the first end of the elastic part 2 is fixed, that is, the position of the first end of the elastic part 2 in the housing 1 is kept substantially unchanged, the second end of the elastic part 2 is provided with a window 201, and the window 201 is specifically a through hole structure opened on the second end of the elastic part 2, in this embodiment, the window 201 is a long hole. The wire connecting portion 3 is used for electrically connecting with a wire to be connected, and one end of the wire connecting portion is disposed through the window 201 and elastically connected with the side wall of the window 201 in an extruding manner. Specifically, the wire connecting portion 3 also has two end portions, the first end of the wire connecting portion 3 is fixed, that is, the position of the first end of the wire connecting portion 3 in the housing 1 is kept substantially unchanged, and the second end of the wire connecting portion 3 is disposed through the window 201 of the elastic portion 2, and it should be noted that the opening length of the window 201 needs to be greater than the thickness of the wire connecting portion 3. The pushing part 4 is movably arranged on the shell 1 in a penetrating way, specifically, the pushing part 4 also has two end parts, a first end of the pushing part 4 extends into the installation cavity, and a second end of the pushing part 4 is exposed outside the shell 1.

When a wiring person needs to perform wiring on the wiring terminal, force can be applied to the second end of the pushing piece 4, and at the moment, the pushing piece 4 integrally moves towards the mounting cavity until the first end of the pushing piece 4 is abutted against the elastic part 2. When the pushing member 4 is pushed further, the elastic portion 2 can be elastically deformed under the pushing of the pushing member 4, the elastic deformation causes the second end of the elastic portion 2 to move in the direction substantially vertically upward in fig. 1, and the window 201 on the elastic portion 2 moves synchronously. Since the window 201 has a large size, the deformation and movement of the elastic portion 2 do not generate a large pushing force on the wire connecting portion 3, and the position of the wire connecting portion 3 is substantially maintained, so that the side wall of the window 201 moves relative to the wire connecting portion 3, thereby forming a space between the side wall of the window 201 and the wire connecting portion 3. At this time, the operator may insert the wire to be connected into the space, and then, stop applying force to the pushing member 4, the pushing member 4 may be reset by the elastic force of the elastic portion 2, and the second end of the elastic portion 2 may be moved and reset in a direction substantially vertically downward in fig. 1, so as to clamp the wire to be connected between the side wall of the window 201 and the wire connecting portion 3, and the wire connection is completed. The wiring terminal does not need to use an external wiring tool during wiring, is simple to operate, has less limitation, is beneficial to improving wiring efficiency, and can avoid the phenomenon of incapability of wiring due to the fact that no external wiring tool exists.

Alternatively, as shown in fig. 3, the elastic part 2 is a spring plate in a ring shape, and a first end of the elastic part 2 is disposed through a window 201 disposed on a second end thereof. With the first end of elastic part 2 as the border, divide into window 201 and be located first window 2011 and second window 2012 of the first end both sides of elastic part 2, first window 2011 is used for supplying the second end of wiring portion 3 to pass, and the second end of wiring portion 3 passes behind first window 2011 and abuts with the first end of elastic part 2. Of course, in other embodiments, the second window 2012 may be used for the second end of the wire connecting portion 3 to pass through by properly adjusting the shape and the installation position of the wire connecting portion 3.

So set up the mounted position of not only being convenient for quick location wiring portion 3 in window 201, and can utilize the first end of elastic component 2 to provide the direction for the removal of the second end of elastic component 2 to make the removal regularization of window 201, help improving the formation and insert the position accuracy in the above-mentioned space of treating the wiring. When the window 201 of the elastic part 2 moves with the second end of the elastic part 2, the first window 2011 gradually increases and the second window 2012 gradually decreases because the second end of the wire connecting part 3 is substantially kept still; when the window 201 of the elastic portion 2 is reset along with the second end of the elastic portion 2, the first window 2011 is gradually reduced, and the second window 2012 is gradually increased.
